Odd 4K no start

[Grant Lenahan]

Gas + spark + air = bang. it may not bang smoothly, but it will bang.
So one of those is missing ( could of course be timing of the 3).

How did you check the spark - did you SEE a spark jump on a plug  
removed from the motor? Did you measure the voltage on the plug lead?  
Neither of those? Then you don;t really know you have spark.  Also,  
how do you know you have gas - did you pull a plug? The pump can  
pump, yet the injectors dont dispense.  Rare, but possible.
